Migration Statistics Quarterly Report: November 2018

A summary of the latest official long-term international migration statistics for the UK for the year ending June 2018 published by Office for National Statistics (ONS). Data from the Home Office and the Department for Work and Pensions (DWP) are also included.

A correction has been made to the excel and csv data downloads attached to Figures 1, 2 and 6. This was due to a small error when calculating the illustrative adjustment for the unusual pattern seen in non-EU student immigration in the International Passenger Survey data. The trends shown in the visuals and download images for Figures 1, 2 and 6 represent the true pattern. The original data can be obtained by contacting us directly at migstatsunit@ons.gov.uk. We apologise for any inconvenience.

2. Migration is still adding to the population of the UK

Net migration continues to add to the population of the UK as an estimated 273,000 more people moved to the UK with an intention to stay 12 months or more than left in the year ending June 2018. Over the year, 625,000 people moved to the UK (immigration) and 351,000 people left the UK (emigration) (Figure 1).

Available data suggest that net migration, immigration and emigration figures have remained broadly stable overall since the end of 2016

In this release we present the Long-Term International Migration (LTIM) and International Passenger Survey (IPS) data with shading around the line on the charts to represent the uncertainty of the estimates due to the number of people surveyed. The line is the most likely value and the values towards the upper and lower band of the shading are possible but less likely. Other sources of uncertainty are not represented.

Non-EU net migration was the highest since 2004, with 248,000 more non-EU citizens arriving than leaving the UK and at a similar level to that seen in 2011. Increases in immigration for both work and study have been seen in the most recent year, particularly for Asian citizens.

The overall number of EU citizens coming to the UK continues to add to the population as 74,000 more EU citizens came to the UK than left. This was the lowest estimate for EU net migration since 2012 and the lowest immigration level since 2014.

The number of EU citizens coming to the UK for work has continued to decrease; in the most recent period this was driven by a decrease in EU15 citizens coming with a definite job. Non-EU citizens coming to work has seen a gradual increase over the last five years.

Statistician’s comment

“Net migration continues to add to the population and has remained fairly stable since its peak in 2016, with around 270,000 more people coming to the UK than leaving in the year ending June 2018.

“However, there are different patterns for EU and non-EU migration. Due to increasing numbers arriving for work and study, non-EU net migration is now at the highest level since 2004. In contrast, EU net migration, while still adding to the population as a whole, is at the lowest since 2012.

“Decisions to migrate are complex and people's decision to move to or from the UK will be influenced by a range of factors.”

3. Net migration continues to add to the population as more people arrive to live in the UK than leave

To fully understand migration, we need to consider all available data sources. On this basis, our best assessment of all sources is that net migration, immigration and emigration overall have remained broadly stable since the end of 2016.

Non-EU net migration was at its highest level since 2004

Net migration estimates show that 248,000 more non-EU citizens came to the UK than left in the year ending June 2018 (Figure 2). This was the highest non-EU net migration since 2004. This increase was driven by a gradual increase in immigration and decrease in emigration in recent years.

Non-EU immigration has seen a gradual increase over the last five years and was 326,000 in the year ending June 2018, similar to levels seen in 2011. The number of non-EU citizens leaving the UK has decreased over the same time period.

EU net migration was the lowest since 2012 but we still saw 74,000 more people arrive in the UK than leave

Despite net migration for EU citizens being the lowest since 2012, EU citizens continue to add to the population of the UK, with an estimated 74,000 more coming to the UK than leaving in the year ending June 2018 (Figure 3). EU net migration has now fallen to the level seen in 2012 just before the sharp rise in numbers coming to the UK began in 2013.

The number of EU citizens who came to the UK was 219,000. This was lower than levels seen in 2015 and 2016 but higher than in the years up to 2014.

The number of EU citizens leaving the UK has remained broadly stable over the last year, but rose gradually since year ending September 2015.

EU15 and EU2 citizens continued to add to the population with positive net migration for the year ending June 2018. However, some of this increase was offset as more EU8 citizens left the UK than arrived (Table 1). Net migration for EU8 citizens has seen a sharp decrease over the last two years and it is now estimated that 14,000 more EU8 citizens left the UK than arrived. This has been driven by a decrease in EU8 immigration, particularly for work, and an increase in emigration over the last two years.

There could be several reasons for this changing pattern, decisions to migrate are complex and people's decision to move to or from the UK will be influenced by a range of factors.

The annual change in non-EU immigration and total immigration are influenced by the unusual decrease in student immigration in 2016. We do not recommend users make comparisons year-on-year and instead look at the broader evidence and longer time series, which allows a better assessment of trends. See Chart 1 TS for trends.

4. Migration for work remains the most common reason for migration

Immigration to the UK for all types of work increased between 2012 and the year ending June 2016 to a peak of 312,000, but has been lower since and is now 242,000. The decrease was largely accounted for by a fall in the number of EU citizens arriving looking for work, with 37,000 in the year ending June 2018, down from 82,000 at the peak two years earlier. However, there has also been a rise in the number of non-EU citizens coming to the UK for work.

EU citizens coming to the UK for work continues to decrease

The number of EU citizens coming to the UK looking for work has stabilised in the last year for all EU groupings. This follows the decrease seen between the year ending June 2016 and June 2017 when the number arriving more than halved.

The number of EU citizens coming with a definite job was stable in the year to June 2017 while the number looking for work was falling. Since then the pattern has changed and in the latest year, to June 2018, the number with a definite job has decreased (down 32,000), particularly citizens of EU15 countries (down 26,000 to 34,000). The overall number of EU citizens coming to the UK for a definite job is now back to a level similar to those seen in 2013 and 2014, at 77,000 in the year ending June 2018 (Figure 4).

Large fall in the number of EU nationals in employment in the UK

The most recent labour market statistics show that there was a fall in the number of EU citizens working in the UK. The IPS data have shown falling numbers of EU citizens arriving for work-related reasons.

For the period July to September 2018 the labour market release shows:

there were 2.25 million EU citizens working in the UK, which was 132,000 fewer than for the previous year and is the largest annual fall since comparable records began in 1997

there were also 1.24 million non-EU nationals working in the UK, 34,000 more than the previous year

!

The number of migrants working in the UK is not a measure of how many people migrate to work. While the Labour Force Survey (LFS) data appear consistent with the IPS migration flows, users should not use the LFS employment trends as a measure of migration flows. The best measure of total migration flows into and out of the UK is the Long-Term International Migration (LTIM) estimates. Not all data sources are directly comparable and users should be aware of these differences before drawing conclusions.

Non-EU citizens coming to work remains stable in recent years

Looking at all available sources (Figure 5) comparing the IPS with work visas and NINos, we conclude that immigration of non-EU citizens for work has remained broadly stable since 2015 and seen a small gradual increase since 2013 following a steady fall from the early to mid-2000s.

Although non-EU immigration for work has remained fairly stable since 2015, there has been an increase in the immigration of Asian, particularly South Asian, citizens over the last year for work-related reasons. The IPS shows an increase for those coming with a definite job.

The latest comparable Home Office data (to the year ending September 2018) for work visa grants for 12 months or more also saw an increase (7%). Visa grants for Tier 2 (Skilled) account for more than half of all work visas and saw an increase of 15% compared with the year ending September 2017, in particular, there were increases for Indian nationals.

There was also an increase in the number of certificates of sponsorship used in applications for Tier 2 (Skilled) work in the human health and social work sector (up 45% in the year ending September 2018). This is likely relating to an increase in the number of doctors and nurses coming to the UK following the removal of doctors and nurses from the Tier 2 cap.

Our assessment based on reviewing data from all sources is that non-EU long-term student immigration remained broadly stable from 2013 to 2017. Based on evidence from Home Office visa data and Higher Education Statistics Agency (HESA) data, we produced an illustrative revised trend (reported further in July 2018) for the International Passenger Survey (IPS) non-EU student immigration estimate (Figure 6).

Non-EU long-term student immigration remained broadly stable from 2013 to 2017 with an increase in the last year

The most comparable Home Office visa data for the year ending June 2018 show there was a 7% increase in the number of study visas issued over the year. The latest Home Office data, for year ending September 2018 suggest this trend has continued as there was a 10% increase in the number of Tier 4 (Sponsored Study) visas issued for 12 months or more, the highest level since 2011. This increase was driven by visas issued to Chinese and Indian nationals.

The IPS estimate of EU citizens coming to the UK to study over the last 10 years has remained relatively stable.

Home Office Immigration Statistics release Release | Released 29 November Includes both short-term and long-term visas (including dependants) for non-EEA nationals and is available for year ending September 2018. The release includes more detailed statistics by visa category, citizenship and industry sector. The release also includes data on citizenship, asylum and resettlement, detention and returns.

It is important to note that estimates by quarter are not as robust as our estimates for rolling years and are not official statistics. This is due to the small sample sizes involved and because the complete methodology applied to our estimates for full years cannot be applied to our estimates for individual quarters.

!

We recommend users do not use these data and instead refer to the rolling years quarterly tables. Due to the seasonal nature of international migration and the small sample sizes involved for individual quarter data, users should be cautious with any interpretation of individual quarter estimates, especially where the corresponding confidence interval is large in comparison with the estimate.

7. Glossary

Long-term international migrant

Office for National Statistics (ONS) migration statistics use the UN recommended definition of a long-term international migrant: “A person who moves to a country other than that of his or her usual residence for a period of at least a year (12 months), so that the country of destination effectively becomes his or her new country of usual residence.”

EU citizenship groups

EU estimates exclude British citizens. Citizens of countries who were EU members prior to 2004, for example, France, Germany and Spain, are termed the EU15; Central and Eastern European countries who joined the EU in 2004, for example, Poland, are the EU8; EU2 comprises Bulgaria and Romania, who became EU members in 2007.

Work-related migration

In the International Passenger Survey “Work-related” migration includes those people who migrate with a “Definite job” to go to already and those who migrate “Looking for work”.

8. Measuring these data

The sources of data included in this release are not directly comparable but taken together provide a better indication of trends than any single source alone. This approach is explained in the Report on international migration data sources: July 2018, which sets out our latest understanding of the quality of International Passenger Survey (IPS) migration estimates.

The Government Statistical Service Migration Statistics Transformation Programme is working towards putting administrative data at the core of international migration statistics. In December 2018, Office for National Statistics (ONS) will publish their findings from the feasibility research on using linked administrative data to provide international migration flows and be seeking feedback on user needs across the international migration evidence base.

Home Office data

Home Office immigration statistics provide the numbers of people who are covered by the UK’s immigration control and related processes, based on a range of administrative and other data sources. Where direct comparisons are made to the IPS data, Home Office visa data are for main applicants only and for long-term visas (one year or more). The User Guide to Home Office Immigration Statistics provides more details.

Department for Work and Pensions data

The Department for Work and Pensions (DWP) National Insurance number (NINo) statistics count the volume of NINos registered to adult non-UK nationals. Further information including detail on data sources, uses and limitations of the series is provided in the background information.

9. Strengths and Limitations of ONS international migration data

The International Passenger Survey (IPS) and the Long-Term International Migration (LTIM) estimates are currently the only sources of data to provide both long-term immigration and emigration and so net migration estimates for the UK.

The IPS is a sample survey and as such provides estimates. When the estimates are broken down beyond the headline figures they are subject to greater levels of uncertainty.

To ensure confidence in our estimates we review all available data sources to make the best assessment of migration in the UK. For example, Home Office administrative data on non-EU citizens travelling is more detailed and do not have the known possible variability present in estimates made from sample surveys.

The accuracy of long-term migration estimates

Surveys gather information from a sample of people from a population. It’s not possible to ask every person travelling in and out of the country to fill out a survey. This means we have to estimate total changes, which can be affected by the group of people we sample. We use confidence intervals to measure uncertainty around the estimate. Users are advised to be cautious when making inferences from estimates with relatively large confidence intervals.

Revisions to net migration estimates in light of the 2011 Census were made in April 2014. The report, a summary and guidance (PDF, 56KB) on how to use these revised figures are available.

Uncertainty in ONS migration statistics

In this release we present the LTIM and IPS data with shading around the line on the charts to represent the uncertainty of the estimates due to the number of people surveyed, based on 30%, 60% and 95% confidence intervals. The line on the chart is the most likely value and the values towards the upper and lower band of the shading are possible but less likely.

Other sources of uncertainty are not represented, a few examples of this include: limitations of the survey methodology, potential misunderstandings of the questions, accuracy of interviewees’ answers and uncertainties caused by combining data from different sources.

Adjusting the LTIM and IPS estimates

Because of the unusual pattern in student migration reported in July 2018, we produced an illustrative revised trend for the IPS non-EU student immigration estimate. For the year ending September 2016 estimates onwards, we have taken the year-on-year percentage change in Home Office non-EU long-term student visa data and applied this rate of change to the IPS estimates for non-EU immigration for study. The illustrative revised trend shows a relatively stable pattern over this time period for IPS non-EU student immigration.

As non-EU student immigration feeds into overall immigration and net migration estimates, we have also produced illustrative revised trends for these estimates. These are for illustrative purposes only and we have not made any changes to the published IPS or LTIM figures. We plan to review this and consider whether a formal adjustment should be made.
